MACHINE FOR USE IN CONNECTION WITH' DERRICKS.

SPECIFICATION forming part of Letters Patent No. 769,264, dated September 6, 1904;

" Application filed'Maroli 24, 1904.

To all whom} it may concern:

Be it known that we, RICHARD LAH'EY, a resident of New York,county and State of New York, and EDWARD GRArrIUs, a resident of Sault Ste. Marie. county of Chippewa, and State of Michigan, citizens of the United States, (our. temporary address being Ford, in the county of Clark and State of Kentucky,) have invented certain new and useful Improvements in Machines for Use in Connection with Derricks, of which the following is a specification.

One of the main features of our invention consists of novel and useful mechanism to advantageously supersede certain mechanism now in use ondouble-drum hoisting-machines.

Another of the main features appertains to the means employed and their arrangement relatively to the bull-wheel of a derrick.

The several features of our invention and employment conjointly or otherwise will be apparent from the following description and claims.

We will now proceed to describe our inven tion in detail.

In the accompanying drawings, in which similar characters of reference indicate corresponding parts, Figure 1, Sheetl, is a view in-perspective of a hoisting-engine, apparatus, derrick, and its apparatus, illustrating our invention. The following-named figures are on a larger scale. Fig. 2 is a perspective view, onan enlarged scale,of the hoisting-engine and itsapparatus shown in Fig. 1. Fig. 3 is a the derrick, thelower portion of the boom, and the bull-wheel. Fig. 4, Sheet 2, is a side elevation of the wheels and the adjacent portionof the chain for operating the bull-wheel. This figure also illustrates a part of the mechanismemployed for operating the clutches which set either of these wheels in motion orput either orboth at rest. Fig. 5 is a top view of the mechanism presented in Fig. A and of one of the foundation-pieces; but the parts N and P and the adjacent portions of chain Q, are omitted from this figure. Fig. 6 is a horizontal section of either driving sprocket- Serial No. 199,836. (No model.)

wheel, its clutch-wheel, a part of its shaft, and the mechanism on the shaft for operating the clutch. Fig; 7 is an edge View of either of the levers directly connected to a nut on a shaft and which nut is adapted to advance andretract the clutch. Fig. 8 is a side elevation of the lever shown in Fig. 7. Fig. 9 is a side elevation of the lever operating the links respectively connected to the levers illustrated in Figs. 7 and 8, Fig. 10 is a view of the preferred form of teeth present on the periphery of either of the sprocket-wheels. This view is one looking directly at the periphery of the.

i wheel and an axial plane coincident with the' wheel. Fig. 11 is a perspective view of a journal box or bearing viewed at a point in the vicinity of the clutch located on the shaft which turns in this box. Fig. 12 is a perspeci tive view of that end of the screw-sleeve which 1 is secured to this box.

the various advantages resulting-from their I A indicates a suitable basal foundation.

On this are located the journal-boxes B. In

perspective view showing the basal part of 1 In the present illustrative instance This In the present illustrative This collar preferably abuts the box B. At

the other end of the box is a sleeve T, carrying a male screw-thread T and provided with a radial flange T The upper half of this radial flange is, as shown, preferably smaller than the lower half. The radial flange preferably abuts the box B at that end ofit which is opposite to thecollar S. This flange T is secured in place, and the preferred means are as follows: A screw is located in the flange and screwed into the boxing B at B On the flange T are cast square lugs T, which fit in a groove between the upper and lower parts of boxing B and prevent the flanges T from turning. This groove is preferably recessed out of the lower half of the box or bearing B. Of course the shaft which the sleeve T embraces turns freely within it.

V indicates a nut having a female screwthread V and a radial flange V This nut V is screwed onto the screw-thread T of the sleeve T. The flange V is at a distance from the flange T and abuts, preferably, directly against the side of the adjacent member G of the clutch E. This member G is mounted on the shaft and is compelled to turn with it; but it can slide along the shaft toward and from the fixed sleeve T. One'or more feathers or keys between the shaft ,and the clutch member G and projecting into both allow the clutch member G to thus move along the shaft in the direction of the length'of the latter. Beyond this clutch member G is the clutch member H,- and the adjacent faces of these members are shaped so as to frictionize each other when brought into contact. hen the clutch membersare apart, there is a space between them, somewhat as shown in Fig. 6.

The preferred construction of the friction-face the clutch H a sufficient bearing on the shaft O. This clutch H turns loosely on the shaft except when forced by the other members of the clutch to rotate with it. A convenient means for preventing the clutch H from slipping off the shaft is the disk I, secured to the shaft by bolts 1 When the nut V is screwed up against the sleeve T and the clutch memmember G. The .means for operating these clutches are as follows: On a framework J, connected to, and supported by the boxes B B,

. down on this lever.

by an adjustable connection.

I locate a journal-bearingJ In this bearing is a pivot or journal J, connected toan upright lever J". Connecting rods or strips J' J are present. One of these extends from the lever J 4 to lever K of the sleeve V, and the other of these extends from the lever J to the lever K of the other sleeve V. These levers K are each provided with rings K, and the latter are preferably split rings and provided with a bolt K, passing through the extensions or lugs K 01" these rings and secured by a nut K. Each ring K embraces its adjacent sleeve V, and with the bolt 1C K the ring is clamped on its sleeve in the proper position and tightly, so that the ring and sleeve turn together. Thus by moving the lever J 4 the levers K will be moved and the rings and their sleeves turned. The throw of the levers K will be greater or less according as the pivot J, whereby they are connected to the lever J, is located higher up or lower Such change of location is readily made by putting this pivot into the desired one of a number of holes (lettered J and located in the lever J as shown. o prefer to connect the lever J to the shaft J" This is preferably as shown and consists of the sleeve J", split at its lower end and provided with the The lever J" being set in the proper are approximated, and the lever J is thus set on the shaft. The shaft J may be positively operated by any suitable means. One means 1 is a lever J fixed on the shaft J at J.

It is to be noted that when both of the levers K are above the horizontal plane of the shaft, as shown, one of the nuts screws forward in a direction the opposite of the other.

If one of the lovers was above and one below said plane, the screws of the nuts might both. be in thesame direction.

We will now proceed to describe another feature of our invention.

Onthe clutch Eto wit, on the outer member (in the present illustrative instance the member H)we fix a gear-wheel L of the sprocket order, adapted to engage with the links of a-suitable chain Q, and on the clutch F (member H) we fix a similar gear-wheel M. Each of these gear-wheels L and M is preferably attached to its respective member H by bolts. At a suitable place 1 locate an idle wheel N. This latter is pivotally connected to a journal-bearing, adjustable so that the wheel N can be moved nearer to or farther from the wheels L and M. The adjustment can be made by screw; but it can be made, as shown, by perforations P in the pieces P, for there are two of these-one on each side of the idle wheel N and these are adapted to receive the pivot N The pivot N if placed in the opposing holes P near the wheels L and M, locate the idle wheel N nearer to them,

and vice versa. The opposite end of each of the pieces P is. duly secured to a foundation.

The sprocket-chain Q passes partly around the gear-wheel, L, and then partly around the idler (idle wheel) N, and, then partly around the gear (sprocket) wheel M, and then onto the bull-wheel 1. The chain Q may be intwo parts. It is duly fixed to thebull-wheel at a proper point or points on the periphery of the latter; Movement of the chain back or forth therefore operates to rotate the wheel. The connection between the chain and bullwheel, so as to rotate the latter, could be accomplished by providing the peripheral surface of the bull-wheel with projections after the manner of a'sprocket-wheel, or the connectionmightbe made by having-the chain embrace the bull-wheelv and be fastened permanently to the bull-wheel at that side of the wheel opposite to where the parts of the chain Q run out toward the winding-drums; but the preferred construction is as shown in Fig. 3. From the bull-wheel the chain Q passes back and around the wheels L, M, and N, as here: tofore described, and then back again to the bull-wheel. The bull-wheel in the present illustrative instance is, as usual, attached to the mast 3, resting in a suitable step or pivothole. The mast or its connection carriesa boom 4. The latter may be located atthe foot ofthemast, as shown, or elsewhere. The

' mast will be, suitably supported, by guys or ates is as follows: When the bull-wheel is tov braces. In the drawings braces are shown.

It is noted that the function of the bull-wheel is to rotate the mast and the boom. In connection withthe mast and the boom and the engine there willhe present suitable means for hoisting the load to be moved and forlowering it. These are well known. As they constitute no part of the present invention, further mention ofthem is omitted.

The manner in which our invention operbe turned a given direction, the lever J is moved toward the boiler. This, screws. the nut V onthe sleeve T away from the boxing B and tightens its clutch E and at t'he'same time screws up the nut on, the shaft-D toward the boxingB and loosens the clutch F. The en.- gine. moving rotates the sprocket wheel L positivelyand moves the chain Qin the desired direction, thus rotating. the-bull-wheel and turning themast and moving the boom as desired. 'To move the boom, mast, and bull-wheel in an opposite direction, the lever J is moved into a position the reverse of that which it heretofore occupied. Such a move: ment causes the nut V on sleeve Tof shaft D. to force the adjacent clutch member G against clutch member H and'the nutV. of shaft C tomove back and liberate the adjacent clutch member G from its clutch member H. Thereupon the sprocket-wheel M will rotate in a direction. the sameas that .in which: the wheel L revolved. The chain Q will thus be moved in an'opposite direction and the "hull, mast, and boom-will be' moved in the like opposite direction. of both of the wheels L and M, we move the lever J to a mid-position. (Seen in Figs. 2 and 45.). Then the nuts VV are in such a position as to leave both members G G out of engagement with their opposingclutoh members 'H H. It will be understood that while the engine continues iJOTGVOlVG in one direction the shafts-C and D, driven thereby through gearing, are so geared as that the shaft 0 revolved in a direction the same as that of the shaft D.

Some of the advantages of our invention are the following: The construction of the means for operating the clutches'is not only novel,

rate. When the hoisting apparatus is first setup and thereafter, all surplus slack present in the chain Q is taken up by this auxiliary wheel N. The necessary tension of the chain Q relative to the apparatus can bereadily adjusted by setting the wheel N nearer to or farther from the wheels L and M, as will be well understood. What we claim as new and of our invention, and desire to secure by Letters Patent, 'is
